Hacked tornado sirens taken offline in two Texas cities ahead of major storm

The latest worrisome example of the vulnerability of critical infrastructure to cyberattacks comes from Texas, where an unknown threat actor last week managed to hack into a total of 30 tornado emergency sirens in two towns, and subsequently set off the alarms in the middle of the night.

As a result of the hack, local authorities needed to take the sirens offline one day before a a major thunder storm was bound to hit the region. Since storms of that kind sometimes create tornadoes in the area, the cyberattack could have had very serious consequences. Luckily, no tornadoes formed during the bad weather, so the emergency sirens were not needed.
